 ANOPLURA; AND CONCLUDING OBSERVATIONS.

 preceding chapters still require further division 

 before we arrive at families; this is particularly 

 the case with the Papilionites, Cimicites, and 

 Cicadites : other orders limited to a single genus, 

 as Panurgites, may, perhaps, eventually, when 

 better known, merge in some neighbouring order. 



813. Besides the orders already described under 

 their respective classes, there are others which do 

 not appear to range under either class ; nor do 

 they appear intermediate between either of the 

 classes connecting them together: these are

814. Ticklers (Thripsites). Larva and pupa 

 unknown. Imago with antennae eight-jointed ; 

 mandibles long, corneous, and possessed of hori- 

 zontal motion ; fore and hind wings membranace-

 two-jointed. Inhabits flowers, feeding on the
